STEP3

•Remove the dust cover(white cap) from the OFC cable. •Be aware don’t touch the top point OFC.

Internal Only?

STEP4

•Connect the OFC connector safely to the LC1 connector at RRU end. • Don’t bend the OFC cable at connector end.

Internal Only?

STEP 5

•Fix the outer cap and fasten it properly to the RRU. • Make sure that OFC cable not getting bend more then its specified radius. •Weatherproofing above the cap as per weatherproofing process. Note:- Same procedure we have to follow for all sector RRU as well as for cascading.

OFC Cable installation Procedure at BBU
